300W TFX power supply for small-form-factor builds

This Silverstone TFX unit delivers 300W of continuous power at a 40°C operating temperature and is rated for 24/7 operation. It carries 80 PLUS Bronze certification and includes a single PCIe 6-pin connector for graphics cards. The 80mm fan runs at a minimum of 18 dBA for quiet performance.

Fits standard TFX bays with sleeved cables

Installation follows the standard TFX form factor so it slides into compatible desktop or server chassis. All-black sleeved cables improve routing in tight spaces. The 80mm fan exhausts heat through the rear grille; ensure the case vent aligns with the fan for proper airflow.

Verify TFX clearance and PCIe power needs

Confirm your chassis accepts a TFX power supply before ordering. Check that the single PCIe 6-pin connector matches your graphics card requirement. Active PFC is built in, so the unit works across typical mains voltages without a voltage switch.
